I am not so sure if this was a legit copy or it's just a bad clone. I tried all firmware from edy555, Dislord, Hugen79, qt, and tinysa (complex) and tried to measure clone copy of diamond antennas and it all shows below 1.5 VSWR. Is there any way I can modify this hardware so I can still utilize it to its purpose? Is this hardware can be still useable or trash?
